The indicator funtion is a feature on the Astra Mk5. However, Vauxhall listened to Astra drivers feedback and decided to change this feature for the Astra Mk6 as follows :
If the lever is moved past the resistance point, the turn signal is switched on constantly. When the steering wheel moves back, the turn signal is automatically deactivated. For three flashes, e.g. when changing lanes, press the lever until resistance is felt and then release. Having a trailer connected, turn signal flashes for six times when pressing the lever until resistance and then release.
